The door incorporates five steps and is hinged to open outward and down. To prevent pressurization leaks between the door and the fuselage, a rubber seal surrounds the door and inflates by air pressure from the airframe de-ice system through a heated pressurization valve when the door is fully closed. A reservoir located below the cabin floor adjacent to the door is charged to 18 psi from the airframe de-ice system providing sufficient air pressure to the door seal for approximately four door closing cycles when the aircraft is parked and both engines are shut down. The reservoir may also be pressurized from an independent air pressure source through a charging valve accessible through the forward galley equipment stowage area. To open the door from inside the airplane, move the internal handle upwards from LOCKED to OPEN position, this deflates the seal and rotates the door upward and outboard, after which it can be lowered. To open the door from the outside the airplane, pull the recessed external handle out and down then support the door while being lowered. Reverse the procedure to lock the door from outside or inside. Two proximity sensors incorporated with the door signal the proximity switch electronic unit (PSEU) of a door unsafe condition by illuminating the PASS DOOR warning light in the flight compartment. A fabric curtain is installed at the airstair door to reduce draft when the airstair door is opened. The curtain is suspended from a track secured to the ceiling panel. Two fastening straps are attached to the curtain to secure the curtain in the stowed position at the draft bulkhead. The curtain must be stowed during take-off and landing. Flight compartment entrance door The flight compartment door is hinged by its left edge on three hinges and opens aft into the cabin. The door may be removed by means of quick release pins, which form part of the two upper hinges. The door is equipped with a lock lever on the flight compartment side to secure the door against entry from the cabin. A key is provided to open the lock from the passenger cabin side. In an emergency, the door may be removed by first lifting and locking the quick release hinge pins of the two upper hinges. Once the upper hinges are free, rotate the door aft on the pivoting lower hinge and lift the door clear of the lower hinge pin. Baggage compartment internal access door A door incorporated with the divider bulkhead provides access to the baggage compartment from the cabin. The door is hinged on the right side and opens into the cabin. The door also incorporates the aft flight attendant's seat. Page 3 Dash8-200/300 - Airplane General Baggage door An external baggage door is provided at the left side of the baggage compartment in the rear fuselage. The door lies flush with the fuselage skin when closed and opens by retracting inward and upward into the ceiling. The retracted door provides an opening of 1.27 m x 1.52 m in the fuselage side. Two proximity sensors, positioned around the doorframe, signal the PSEU of a door unsafe condition, which illuminates the BAG DOOR warning light in the flight compartment. Service door A service door, located at the aft right hand side of the fuselage, permits easy access to the rear-mounted buffet. The door is a plug type and opens inward and upwards along tracks on the ceiling. The door is held in the raised position by detents in the track and positive latching mechanism. Raise the door to the fully open position to properly latch the door. Before closing, support the door before releasing the latching mechanism. Door opening and closing can be performed from the inside or the outside of the aircraft (see service door operation figure). A sensor, positioned on the door frame, signals the PSEU of a door unsafe condition which illuminates a SERVICE DOOR warning light in the flight compartment. Emergency exit doors and escape hatch Three emergency exit doors are fitted in the cabin. All emergency doors can be opened from either inside or outside. The forward exit door is located at the right side of the cabin, between seat rows 1 and 2. This door is a type I, outward opening type. A sensor signals the PSEU of a door unsafe condition, which illuminates a FWD EXIT DOOR warning light in the flight compartment. Two type III, inward opening, emergency escape doors are located under the wing. No warning systems are fitted to indicate the status of these doors. The escape hatch is located in the flight compartment ceiling. It can only be opened from the inside of the aircraft. For more details on emergency exit doors and escape hatch refer to section 12-7 emergency equipment. Service and refuelling doors Several hinged doors are fitted for servicing, inspection and refuelling purposes. All open outward and are locked closed by quick release fasteners.

The exterior lights are controlled from two exterior lights panels located on the overhead console. Glareshield mounted lights illuminate the ice detector posts mounted on each windshield wiper arm. The lights are powered from its respective essential DC buses and controlled from momentary contact pushbuttons labelled W/S WIPER ICE DETECT LIGHT. The pushbuttons are situated on pilot and co-pilot side consoles. LEFT RIGHT Exterior lights Page 9 Dash8-200/300 - Airplane General Page 10
